Trout do most of their feeding underwater, and the Pheasant Tail Nymph is one of the best ways to reach them. Frank Sawyer's elegant, slim pattern imitates the mayfly nymphs that make up so much of a trout's diet, and it is effective across an enormous range of water. Fished under an indicator or on a tight line, it is a first-choice searching nymph.
What it imitates
The Pheasant Tail suggests a mayfly nymph, the slender, swimming or crawling immature stage that trout eat constantly. Its narrow, tapered body and wing-case profile read as a natural nymph drifting in the current, and a bead-head version gets it down to the fish quickly.
How to fish it
Fish it dead-drift near the bottom, that is where the naturals are. Under an indicator for classic nymphing, or on a tight line for euro nymphing, the goal is the same: a drag-free drift right in the trout's feeding lane. It is often fished as the dropper below a bigger, heavier nymph.
Tip Get it deep and drag-free. Most nymphing failures come from the fly riding too high or dragging unnaturally, add weight or a heavier bead until you are ticking bottom, and mend to keep the drift natural.
Sizes and colors
The natural pheasant-tail brown in a range of sizes is the standard; bead-head and flashback variants add versatility. Pair it with a Hare’s Ear to cover both slim and buggy nymph profiles.
